Placement of the ACPA4000 Where to locate the unit When deciding where to locate the unit, consider your cooling needs, air flow, the location of the electrical outlet, and access for the condenser intake and exhaust. Cooling needs. Position the unit as close as possible to the main source of heat that requires cooling. Air flow. Position the unit so that its rear is at least eight inches (20 centimeters) away from a wall or other equipment. Location of electrical outlet.
Intake and Exhaust Vents Hose connections The Portable Air Conditioning Unit requires the installation of an intake hose and exhaust hose for the condenser. Refer to the drawing to identify the intake and exhaust sides of the system. 6 Building structural support Air deflector 10-gauge (min.
Introduction: Intake and Exhaust Vents Assemble the ceiling adapter Attach the air deflector to the exhaust side of the ceiling adapter using three M6 nuts. The air deflector must face away from the air intake and obstructions such as a wall or piping. Failure to position it in this way will reduce cooling capacity and could cause unit Caution alarms. Install the adapter in a drop ceiling Use the ceiling adapter to provide an intake and exhaust outlet for the condenser.
Introduction: Intake and Exhaust Vents 3. Secure the ceiling adapter to the building’s structural support (not the drop ceiling), using 10-gauge (minimum) steel wire. 4. When using 2 × 4 foot ceiling tiles, insert a cross member (not provided) for added support. Assemble the ducts 1. Thread the duct collars counterclockwise onto each of the ducts until they bottom out. The hoses used are directional and will reduce airflow if not properly installed. Expand the length of hose to fit the required space.
Introduction: Intake and Exhaust Vents 3. Slide the duct collar of each hose over the ceiling adapter sleeves and turn to lock in place. Note Connect the air diverter side of the ceiling adapter to the exhaust. 4. Slide the duct collars onto the other end of the ducts over the condenser flanges and turn to lock in place.
Drain Line The unit ships with 50 feet (15.24 meters) of hose for removing condensate from the unit. You can attach a different hose to the unit: • if you use a 1/4-inch, clear, polyurethane hose. • if the hose length does not exceed 50 feet (15.24 meters), and 16 feet (4.88 meters) vertical maximum. • if you cut off all excess drain line and avoid kinking or pinching the drain line for proper operation. How to attach the drain line.
Accessories Temperature/Humidity probe The Remote Temperature/Humidity Probe (AP9512TH) monitors the room temperature and relative humidity. This remote probe gives you the ability to monitor the environment surrounding the cooling unit to ensure that the conditioned air is cooling the desired area. . The APCA4000 cannot be controlled based on the temperature measured by the probe. Note To install the probe: 1. Determine a location that will allow you to neatly route and secure the 12-ft (3.
Introduction: Accessories Overview of relays and contacts The ACPA4000 provides connectors on its main control board for output relays and input contacts. The connectors can be used with any dry-contact closure-type sensors. The connectors are designed to monitor circuits that have no voltage potential of their own. Connecting to any circuits other than a dry closure type may result in damage to the main control board.
Introduction: Accessories To connect an output relay: 1. Attach a 12-position terminal block (provided) to the output relay connector. 2. Strip the wire insulation on your sensor 0.25in (6mm). 3. Connect your sensor wires to the pins associated with one of the four positions on the output relay connector. 4. Configure the settings for the output relay through the display interface. See “Set Up Contacts and Relays” on page 25.
Start-Up Start-up checklist Before starting the unit, check to see that the following conditions are met: • All electrical connections have been made to local codes and safety standards. • All accessories and duct work have been installed. • Air flow to and from the unit is not blocked. • Condenser drain is connected and not kinked or pinched. How to apply power to the unit Insert the IEC 320 C19 connector of the power cord into the back of the unit.

Maintenance and Troubleshooting Maintenance Replacing the air filter Replace the air filter every 90 days or sooner if an alarm occurs. Keep the air filter clean to maximize the performance and life of the unit. For maximum unit efficiency and to prevent equipment damage, always replace the filter with the correct size and type recommended for the unit. Note 1. Slide out the filter element from the rear of the unit. 2. Insert a new air filter (APC part number ACPA4000RF).
Maintenance and Troubleshooting: Maintenance Cleaning the condenser filter The condenser filter traps large items that may fall into the ducts. Periodically check and clean the filter to prevent damage to the condenser. 1. Turn off the unit, and unplug it from its electrical outlet. 2. Remove the condenser air intake duct from the back of the unit. 3. Clean the filter (inside the air intake duct) using your hand or a dry cloth.
Troubleshooting Problem Possible cause Corrective action Unit does not respond Unit is not plugged in. Securely plug receptacle into the outlet. Main power is off. Check building fuse or circuit breaker. Air exhaust or intake is blocked. Clear all objects away from air grills; move the unit away from the wall. Air filters are dirty. Clean or replace air filter. Heat load is beyond unit’s capacity Additional cooling capacity required. Fan speed is too low. Increase fan speed.
